Vis\u00e3o geral da v\u00e1lvula de controle aut\u00f4noma:<\/p>\n

 <\/p>\n

A v\u00e1lvula de controle de press\u00e3o aut\u00f4noma ZZYP \u00e9 composta principalmente por uma v\u00e1lvula de controle, um atuador e uma mola para ajuste de press\u00e3o. \u00c9 adequada para l\u00edquidos, gases e vapor n\u00e3o corrosivos. Controle de press\u00e3o antes da v\u00e1lvula na tubula\u00e7\u00e3o do sistema (quando a press\u00e3o antes da v\u00e1lvula aumenta, a v\u00e1lvula de controle abre) ou ap\u00f3s a v\u00e1lvula (quando a press\u00e3o ap\u00f3s a v\u00e1lvula aumenta, a v\u00e1lvula de controle abre). Amplamente utilizada em petr\u00f3leo, ind\u00fastria qu\u00edmica, energia el\u00e9trica, metalurgia, medicina, alimentos, t\u00eaxteis, m\u00e1quinas, HVAC. Os tipos de a\u00e7\u00e3o incluem regula\u00e7\u00e3o de press\u00e3o ap\u00f3s a v\u00e1lvula redutora de press\u00e3o (tipo B) e regula\u00e7\u00e3o de press\u00e3o antes da v\u00e1lvula de al\u00edvio de press\u00e3o (tipo K).<\/p>\n

 <\/p>\n

Caracter\u00edsticas da v\u00e1lvula de controle de press\u00e3o aut\u00f4noma:<\/p>\n

 <\/p>\n

Comparada com a v\u00e1lvula de controle manual, a v\u00e1lvula de controle de press\u00e3o aut\u00f4noma tem a vantagem de poder ser ajustada automaticamente; comparada com a v\u00e1lvula de controle el\u00e9trico, sua vantagem \u00e9 que n\u00e3o requer energia externa. A v\u00e1lvula de controle aut\u00f4noma utiliza a press\u00e3o e a temperatura do meio que flui atrav\u00e9s da pr\u00f3pria v\u00e1lvula como fonte de energia para acionar a v\u00e1lvula a trabalhar automaticamente, n\u00e3o necessitando de fonte de energia externa nem de instrumentos secund\u00e1rios.<\/p>\n

 <\/p>\n

Fun\u00e7\u00e3o da v\u00e1lvula de controle de press\u00e3o aut\u00f4noma:<\/p>\n

 <\/p>\n

Todas as v\u00e1lvulas de controle aut\u00f4nomas utilizam o sinal de feedback (press\u00e3o, press\u00e3o diferencial, temperatura) na sa\u00edda da v\u00e1lvula para transmitir ao atuador atrav\u00e9s do tubo de sinal, acionando o disco da v\u00e1lvula para alterar a abertura da v\u00e1lvula e atingir o objetivo de controlar press\u00e3o, fluxo e temperatura. Em sistemas de circula\u00e7\u00e3o de \u00e1gua fechados (como sistemas de aquecimento de \u00e1gua quente, sistemas de \u00e1gua gelada de ar condicionado), o uso correto desta v\u00e1lvula pode facilmente realizar a distribui\u00e7\u00e3o de fluxo do sistema; pode realizar o balan\u00e7o din\u00e2mico do sistema; pode simplificar significativamente o trabalho de depura\u00e7\u00e3o do sistema; pode estabilizar o estado de funcionamento da bomba, etc.<\/p>\n
